Finite element modelling on shear behaviour of concrete beam reinforced with glass fiber reinforced polymer bars system / Nurul Izziyante Mat Noor

The computational simulating of reinforced concrete beam reinforced by glass
fibre reinforced polymer (GFRP) bars subjected to static loading dependent on the
modelling of nonlinear constitutive laws of materials by using LUSAS 14.7 Modeller.
Nonlinear behaviour of GFRP bar reinforced concrete beam includes shear cracking
where static loading introduces further complexities, such as stiffness degradation in
concrete. In this paper, the reliability of presented constitutive models for concrete by
using Drucker-Prager Plasticity Model when subjected to static loading that considers
stress distribution is investigated. In the analysis of reinforced concrete structures, a
number of diverse approaches have been used for material modelling. These include of
nonlinear elastic models where this simulation is related to constitutive models based
on elasticity approach. For these aims, finite element (FE) models will be developed in
eight numbers of specimen beam models by having o f steel rebar and GFRP as
reinforcing bars. The results that will be subtracted from FE analysis will be discussed
and reviewed with the results of experimental tests investigated later in laboratory.
